A Painting Interface
for Interactive Surface Deformations
A long-standing challenge in geometric modeling is providing a natural,
intuitive interface for making local deformations to 3D surfaces. Previous
approaches have provided either interactive manipulation or physical simulation
to control surface deformations. In this paper, we investigate combining
these two approaches with a painting interface that gives the user direct,
local control over a physical simulation. The "paint" a user applies to
the model defines its instantaneous surface velocity. By interactively simulating
this velocity, the user can effect surface deformations. We have found that
this painting metaphor gives the user direct, local control over surface deformations
for several applications: creating new models, removing noise from existing
models, and adding texture to an existing surface at multiple scales.
